Visualization of Real-Time Esophageal Location Using Intracardiac Echocardiography on a Three-Dimensional Mapping System: Comparison of Esophageal Location Using Preoperative Computed Tomography and Investigation of Predictors for Esophageal Movement During Catheter Ablation.

ABSTRACT:

Introduction

Pulmonary vein isolation (PVI) using radiofrequency catheter ablation is an effective treatment for atrial fibrillation; however, esophageal-related complications remain a concern. The first objective of this study was to compare the feasibility of two techniques for visualizing real-time esophageal images: intracardiac echocardiography (ICE-Eso) and preoperative computed tomography (CT-Eso). The second objective was to clarify the predictors of esophageal movement on the day of catheter ablation.

Methods and results

Eighty consecutive patients were included in this study. The esophageal location was measured at the centerline of each image on three equally separated imaging sections (upper, middle, and lower sites). Esophageal locations detected on ICE-Eso and
